Now, first of all let me get something clear: I do not ask for any reasons why align
is btter than eqnarray
. All I ask is a simple way to make this work, using eqnarray (It's obviously possible, but I'm not sure how).
\begin{eqnarray}~\label{eqn07}
\begin{tabular}{llll}
$\Psi_{1}(x,\lambda)$ & = & & $ U(x,\lambda)e_{1} $ \cr
& & & \cr
\end {tabular}
\end {eqnarray}
Yet after compiling it, I get the equation centered, instead of left-aligned. I've tried to insert \left{ ... \right}
, but it wouldn't even build, and I just had many errors popping up. Could someone tell me a simple way to do so, wihout using \begin{align}
. I do want to use \begin{eqnarray}
(I've got my own reasons why).

You should add the
fleqn
option to your document class. Regardless, the following is the correct way of usingeqnarray
:You'll notice that the equation is left-aligned, although not flush with the left margin. To achieve this, add
\setlength{\mathindent}{0pt}
to the document preamble as well.Note that you don't need
eqnarray
for a single equation. For this, theequation
environment is sufficient. However, since the spacing ofeqnarray
is inferior to the regular math spacing, it might be better for consistency.
